STREET-SPRINKLING APPARATUS.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed March 4, 1912. Serial No. 681,433.

To all whom it may concern Be it known that I, PEDER T. MoLLnR, a citizen of the United States of America, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Street-sprinkling Apparatus, of which the following is a specification.

This invention relates to a street sprinkling apparatus, the object of the invention being to provide conduits permanently located beneath a street and preferably in the center thereof, said conduits being provided with discharge vents for discharging streams or jets of water in opposite directions, and toward the curb to thereby flush the street and effectually cleanse the same without the necessity of employing horses, vehicles, or sweepers.

A further object of the invention is the provision of improved means for protecting the vent openings of the conduits from being clogged with dirt, and from being battered to a closed condition by the passsage of vehicles.

A still further object of the invention is the provision of improved means for elliciently directing the water discharged from the conduits in a manner to cause it to effectively flush a large area.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing Figure 1 is a transverse section through a conduit located beneath a street, illustrating a special form of protecting and flow directing cap, hereinafter described. Fig. 2 is a diagrammatic view illustrating one method that I may employ for controlling the flow from the conduits by blocks.

Referring to the drawing, 5 designates a conduit having discharge apertures 6 formed therein. A cap plate 7, having overhanging and downwardly curved edges 8, overlies the nozzles.

9 designates the cement, concrete or asphalt forming the street, the face of the street adjacent the conduit being curved at 10 for a purpose hereinafter described. In this form of the device, water, when admitted to the conduit 5 under pressure, is discharged with great force through the apertures 6. The downturned edges of the cap 7 direct the jets of Water against the curved surfaces 10 of the street, these curved surfaces in turn acting to direct the water upwardly and outwardly along substantially the lines indicated at 11 in Fig. 1. This causes the water to be directed, with considerable force, over a large area, thereby effectually flushing the street, as will be readily understood. If desired, the conduits within a given block may be conveniently controlled by valves 17, see Fig. 2, and one block may be flushed at a time. The arrangement of valves for the controlling of different blocks may be varied at will, for it is apparent that many different arrangements of these valves may be made.

From the foregoing description it will be seen that simple and eflicient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is 1. In a device of the character described, the combination with a conduit extending along the street to be flushed and substair tially centrally thereof, the upper face of said conduit being exposed at the surface of the street, oppositely directed discharge apertures formed in said conduit for the purpose of flushing the surface of said street, a cap overlying each pair of oppositely directed discharge apertures, said cap having downwardly curved terminal edges, and the surface of the street adjacent said discharge apertures being downwardly curved to a point on the conduit spaced from said apertures and presenting convex surfaces to said downwardly curved terminal edges of the cap.

2. In a device of the character described, the combination with a conduit extending along the street to be flushed and substantially centrally thereof, the upper face of said conduit being exposed at the surface of the street, oppositely directed discharge apertures formed in said conduit for the purpose of flushing the surface of said street, a cap overlying each pair of oppositely directed discharge apertures, said cap having downwardly curved terminal edges, In testimony whereof I afliX my signature and the surface of the street adjacent said in presence of two witnesses.

discharge apertures being downwardly V curved to a point on the conduit adjacent PEDER MOLLER' 5 said apertures and presenting convex sur- Witnesses:

faces of said downwardly curved terminal H. M. VOLLMER,

edges of the cap. G. U. FRY.
